BEATER FOR CORN-SHELLERS.

SPECIFICATION forming part of Letters Patent No. 233,066, dated October 12, 1880. Application lled July 14, 1880. (No model.)

To aZZ whom it may concern Be it known that I, CALEB C. BURRoUeHs, of Decatur, in the county of Macon and State ot' Illinois, have invented certain new and useful Improvements iu the Construction of Beaters for Corn-Shellers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference bein g had to the accompanying drawings, in which- Figure l represents a longitudinal vertical section of a corn-Sheller having the improved beater. Fig. 2 represents, in transverse section and front view, one of the beaters. Fig. 3 is a perspective view of a piece of wrought iron or steel cut, bent, and shaped for use as a tenacious metal core in forming the beater. Fig. et represents, in transverse section and front view, a modiiication of the beater.

My invention relates to the construction of beaters or feeders of corn-shellers.

The object of my invention is to re-enforce these pieces of a corn-Sheller by means of a tenacious core of wrought-iron or steel, so that if, while revolving, the arms meet obstructions of such size or weight as to crack the cast-iron forming the bulk of said arms, the broken piece will not ily out of the sheller, endangering attendants, or pass through the shelling apparatus and screens, damaging the latter, but will remain united to the hub until a new one can be substituted.

Heretofore wrought-iron in the form of perforated plates or woven wires has been used within molded cast-iron safe-plates, and also within the paddles of disiutegrating-mills, to add strength or hardness to the cast metal, and I am aware that the principle of uniting wrought and cast iron is not new, my invention relating only to the peculiar mode of uniting the arms to the hub of a corn-Sheller beater.

My invention consists in combining with the hub and arms of a corn-Sheller cast-iron beater a permanent core formed of tenacious plate-metal, having its central portion split lengthwise and bent in opposite directions and its outer portions provided with notches or indentations and projections for engagement with the liuid metal cast around it in forming said corusheller beaters.

In the corn-Sheller represented in the drawings, A represents the frame; B, the main shaft, operated through the pulley C. On the shaft B is secured the trunco-conical sheller D, and the latter is surrounded by the conical casin g E.

On the cylinder-shaft are secured beaters or feeders I, which work directly under the hopper G, as shown. These beaters or feeders prevent the corn from arching in the hopper, and prepare the corn for the conical sheller D by partially shelling and forcing the corn to the shelling-surfaces of the cone and casing.

It occasionally happens that blocks of wood, horseshoes, 85e., are dropped with the corn into the hopper. The feeders I, while rapidly revolving, strike these bulky, heavy, or unyielding substances, and one or both arms of a beater become broken off and separated from the hub, and either fly off the hopper or enter and pass between the grinding-surfaces of the sheller, causing great damage.

thereto aud to sieves generally placed :adjoining to the sheller.

Io prevent the breaking of the arms I or their separation from the hub l of the beater, I unite them by a central core of tenacious wrought-iron or steel. This is preferably made, as shown in Fig. 3, of a hat plate, L, split lengthwise at Z, forming bands Z and Z2 to encircle the eye of the hub, and arms Z3, provided with iudentations Z4, in which the melted cast-iron forming the main component part of the beater enters, and in cooling becomes firmly united to the tenacious internal plate.

Each arm of the beater may be united to' the hub by a flat plate, L', independent of the other, as shown in Fig. 4. The plate, extending over the weak point of junction of the arm with the hub, is provided with indentations Z4 adjoining each end, as a lock for the molten cast-iron. One or both of these plates L may be Inade to extend within the eye of the hub, as a key to secure the beaters to the main shaft.

Having noW fully described myinvention, I claim- In combination With the hub and arms of a corn sheller cast -iron beater, the internal Wrought-iron or steel plate, L, split length- Wise in its central position, and the parts bent in opposite directions, having bands l 1o and l2, to encircle the eye of the hub, and arms Z3, provided with indentations, substantially as and for the purpose described.
